historical timeline
President Salvador Allende is elected to power at the head of a Popular Unity coalition of Socialists and Communists.

August: Augusto Pinochet is appointed by Allende as commander-in-chief of the army.

September: In a violent coup, the presidential palace is bombed. Allende is among the first of 1,213 people who die or disappear between September 11 and the end of 1973. Pinochet dissolves Congress, suspends the constitution, bans opposition, arrests trade unionists and imposes controls on the media. Thousands are forced into exile. Four hundred US CIA experts assist Pinochet. The regime embarks on a radical program of denationalization, closely assisted by economists from the University of Chicago.
Orlando Letelier, Chile's former foreign minister and Socialist Party leader in exile, is killed by a car bomb in the center of Washington DC. The Pinochet regime is widely implicated.
Pinochet declares an amnesty to cover all human rights abuses since the coup.

Pinochet launches a new, dictatorial, constitution, which is ratified by a controversial plebiscite.

Britain lifts its arms embargo on Pinochet's regime.
Pinochet is the target of an assassination attempt by the left-wing Manuel Rodriguez Patriotic Front (FPMR).
Pinochet legalizes some political parties. Leaders of the centrist opposition Democratic Alliance reject the initiative as "having no other purpose than the continuation of the dictatorship". The Pope visits Chile and denounces political torture.

Pinochet, due to international pressure, is forced to call a referendum (plebiscite) on his presidency. The country will vote YES or NO to the extension of Pinochet's rule for another eight years.

The pro-Pinochet YES campaign and opposition NO campaign are given equal airtime on Chilean television.
Pinochet loses a plebiscite on his rule with 44 per cent of the ballot.
Veteran lawyer Patricio Aylwin, aged 70, a Christian Democrat, wins a landslide 55 percent of the votes to become Chile's new president. He is sworn in 1990, but Pinochet stays on as army chief.
Chile's National Commission for Truth and Reconciliation publishes a lengthy indictment of Pinochet's dictatorship, officially counting 2,279 deaths (later revised to 3,172) in "political violence".

JUNE 30: "Today the Department of State, the Central Intelligence Agency, the Department of Defense, the Department of Justice, the Federal Bureau of Investigation, and the National Archives are releasing newly declassified and other documents related to events in Chile from 1973-78. These documents are part of a voluntary review of U.S. Government files related to human rights abuses, terrorism, and other acts of political violence prior to and during the Pinochet era in Chile."
